News during Backtest
-
Hello, how can I apply news filter during backtesting?
-
@tec-nacks most news filters dont support that.
Technically its possible, if you get some kind of database of old news records. In fact, I'm willing to code it for you, if you really find such database.

Will work on getting one
and Can you create a News Filter Block that can be used in FxDreema? We really need to have a News Filter Block
-
I wonder why there is still no such Condition block in the default block list. That alone would make many aspiring coders wiling to play around with that
-
I have spoke to FxDreema and he said it because I was the only one requesting it....I'll make a post on it, lets engage with it, tagging him and hopefully he does it in a tingle.
-
I support the motion. Any help in this field would be highly appreciated.
-
Thank you, I've made the post thread here...We can add to it and bring the admin's attention to it

While searching for a solution on how to filter news in backtesting on MT5, I came across this thread.
As it happens, I have access to a database of historical news dating back to 2007.So, my question to you, @roar - are you still capable of writing or designing a block that would prevent an EA from opening new positions, for instance, 1 hour before high-impact news and 1 hour after?
@l-andorrà mentioned in another thread that this is the Holy Grail everyone is searching for on this forum.
Of course, I still refer to backtesting, but If your solution were to also work in the live market, it would be a great bonus for everyone here, I think.
Since the @fxDreema isn't eager to write such a block, perhaps we could create it ourselves?
What do you think? -
@Archer sure, lets do it!

Alright, have fun with it !
Files include news from 2007-01-01 thru 2023-12-31.
Data runs through to the end of this year (news events that haven't occurred yet have their 'Actual' value set to "").
Format is:
"date","time","currency","impact","description","actual","forecast","previous","revised from","event id"Events in the zip file are timestamped UTC; (UTC–5 during winter and UTC–4 during summer).
The credit goes to my old buddy Hanover; hats off to him for sharing the database. I'm just the middleman and the initiator here.
-
@Archer Awesome step... was thinking I'll ask if @roar could help with it initially but I like this move men.
Would Like to suggest if Medium Impact can be added as well and if Forex Factory could be the chosen News Platform as the former one investing stopped working earlier.
I'm looking forward to this move @Archer and @roar
Would be a great addons to FxD

@Archer thank you! That is good data, valuable stuff. I'll try to find some time this week to code it and update here. Please remind me if I dont

Hey @roar , how's that coding goin' ?
Do you think you'll be able to share your work with us by the end of this week ? -
Hi!
I processed the csv file in a custom indicator project, but trying to move the same code to fxdreema causes some weird problems. I think fxdreema cannot handle such big arrays, it needs to be constructed in some other way...
Maybe someone finds the indicator format useful. I will try to better integrate this to fxdreema at some point...
I used the file "All news events 2007-01-01 thru 2023-12-31 timestamped UTC time -- sorted by date, time.csv", renamed to "news.csv" and moved to the Common folder.

@roar Please how can we make use of this newsfilter?

The indicator looks promising.
I'll play around with it soon.
@roar, thank you for your work ! -
I tried to work with this indicator, thinking that the buffers you added would give me some reference point. Unfortunately, they return a zero value.
I had such an idea to stop the EA from opening new positions 60 minutes before and 60 minutes after the news:
I use a similar solution in live market, referencing different news indicator that I possess, and it works very well.
So, it would be great if, for example, buffer 0 created a unix timestamp value with the time of the next upcoming event with HIGH IMPACT. Buffer 1 would do the same but for MEDIUM IMPACT. Then we would have a specific reference to the time, and the above solution should work.
It would be also great if you could add Buffer 3, which filters events based on specific words entered somewhere in the indicator and provides a unix timestamp value only for events that contain those specific words.
For instance, I personally avoid trading when someone from the Fed speaks, or when Lagarde does. So, after entering the word 'FED' or words separated by commas like 'H, Speaks' Buffer 3 would provide the timestamp only for the nearest upcoming event containing those words.
I know that everyone has different preferences when it comes to trading the news, some avoiding or trading only specific events like for example the ADP Non-Farm Employment Change, etc.
That's why I believe such a filter would be helpful for many individuals.Moreover, having these buffers would offer unlimited possibilities for controlling the behavior of the EA concerning news events during backtesting and not just preventing it from opening new positions.
Does what I've written make sense to you?
If so, would you be able to create such Buffers? -
I found another solution on how to filter news in backtesting on MT5.
Full description of how to use it is explained below.
Perhaps this method will prove to be easier to integrate with FX Dreema ?One block like this:
plus txt filtering news content option which I mentioned earlier would be a dream come true !

// 3. if(!) your broker isn't located in central Europe (or the same time zone, with daylight saving time): // adjust the GMT_OFFSET default value definitions (below) to the requirements of your country/region; // alternatively adjust the values in OnInit(): // e.g. // news.server_offset_winter=2; // news.server_offset_summer=3; // why is this information necessary? because the event calendar seems to use GMT time for event dates/time, // however in the strategy tester TimeGMT() returns wrong values and then is the same as TimeCurrent() or TimeTradeServer(), // therefore in the tester GMT time needs to be simulated in order to match with the event data supplied by Metaquotes // 4. keep the event array updated in your main event handler (OnTick(),OnStart(), OnCalculate()..) by calling // news.update(); // by default the updates will be limited to once every 60 seconds, which is usually much more than enough // because most scheduled events are announced already with several days in advance, so that staying even more "current" // usually in reality doesn't change anything; // if a different update frequency is desired, just add this as a parameter, e.g. // news.update(900); for array updates every 15 minutes; // if detailed print log information is desired e.g. during debugging, set the second parameter to 'true' (false by default), e.g.: // news.update(60,true); // there is one exception with some strategies where instant updates are necessary: exactly around the time of the news event in those cases when we need instant access // to the 'actual value' (e.g. in order to compare it to the forecast), then // news.update(0); // is recommended // 5. the total number of accessible historical, current and scheduled near future events is given by the return value of the update function, e.g. // int total_events=news.update(); // this number (minus 1) also represents the highest possible index of the event array, so it's the same as ArraySize(news.event); // to access detailed information about any event, then just address it via its index: // news.event[index].value_id // news.event[index].event_id // news.event[index].time // news.event[index].period // news.event[index].revision // news.event[index].actual_value // news.event[index].prev_value // news.event[index].revised_prev_value // news.event[index].forecast_value // news.event[index].impact_type // news.event[index].event_type // news.event[index].sector // news.event[index].frequency // news.event[index].timemode // news.event[index].importance // news.event[index].multiplier // news.event[index].unit // news.event[index].digits // news.event[index].country_id // news.eventname[index] // // in order to make sense of a country id (which is just a number) and get the currency (=as a 3 character string) of this country // just use the function news.CountryIdToCurrency() // accordingly, in order to get the country id for a given currency, use news.CurrencyToCountryId(); // // there is one thing to mention about the 'index': at the time I'm writing this about 90.000 historical events can be accessed from the Metaquotes servers, // however, this also means the index number can be pretty high and we probably don't want to go through the entire history of all past events until we have found the next upcoming event, // so in order to make this more convenient (/efficient), I added the function // news.next() // which returns the index number of the next upcoming event relative to a given index to start the search with, e.g.. // news.next(last_event_index,"USD",true,0); // in order to find the next following event that affects the dollar pairs, starting the search with index 'last_event_index'; // 'true' and '0' in this case means that the event will be shown on the current chart as a vertical line with the name of the event attached // // IMPORTANT: please note that this method works for both the strategy tester and live trading, // actually the main motivation for this 'workaround' was to be able to test news strategies before deploying them in live trading, // however, by default Metaquotes makes it impossible to directly access historical event data in the strategy tester, so that for testing this workaround // consists in ONCE storing historical data to the harddrive and access them then later offline from this file; // this means that in order to make this work, the EA has to be run at least ONCE in live mode; live mode doesn't mean trading; for example also just having called the news.update() function only once // in the "debugging with live data" mode already is enough to ensure that the event data file exists (as a .bin file in the common files folder); // for actual live trading on the other hand of course the news history file is irrelevant (because then we can also access the data directly, like intended by the built-in functions), but it also 'doesn't hurt'; // as a consequence, there are no differences of how to use this code whether it's for testing or live; I think this makes dealing with events in an EA a lot easier // // Happy news trading, // // Chris // ___________________________________________________________________ #property copyright "username Chris70" #property link "https://www.mql5.com" #define GMT_OFFSET_WINTER_DEFAULT 2 #define GMT_OFFSET_SUMMER_DEFAULT 3 enum ENUM_COUNTRY_ID { World=0, EU=999, USA=840, Canada=124, Australia=36, NewZealand=554, Japan=392, China=156, UK=826, Switzerland=756, Germany=276, France=250, Italy=380, Spain=724, Brazil=76, SouthKorea=410 };
